What is Industry 4.0?
Industry 4.0 is related to the fourth industrial revolution which is associated with the advancements of cyber-physical systems. It describes the rise of automated systems and data exchange technology within the manufacturing industries. Examples of the Industry 4.0 technologies becoming more prominent on factory floors include:
- The Internet of Things
- The Industrial Internet of Things (IIoT)
- Smart Manufacturing
- Connected Manufacturing
- Smart Factories
- Cloud Computing
- Cognitive Computing
- Artificial Intelligence
- Cyber-physical Systems
This automation creates a manufacturing system where all the devices and technology used in production are wirelessly connected and use sensors and monitors to visualize entire processes and provide an overview of a company’s manufacturing. These technologies are always advancing and, with the rollout of 5G, businesses can expect faster response times and real-time communication between systems.
The Evolution of Industry 4.0
To understand the impact of Industry 4.0, it’s important to understand the evolution of industry from 1.0 to 4.0:
Mechanical production facilities were introduced to the world in the late 18th century, paving the way for steam-powered machines to help workers in manufacturing. The increased production efficiency these machines provided helped small businesses grow into large organizations with owners, managers, and employees. Industry 1.0 is also deemed as the beginning of industry culture.
Industry 2.0 began at the start of the 20th century with the development of machines running on electrical energy. Electrical machines were more efficient to operate and maintain than their steam-powered counterparts, paving the way for a more cost-effective, productive factory floor. The first assembly line was built during this era, further streamlining the process of mass production.
Industry 3.0 was centralized around the advances in the electronics industry in the last few decades of the 20th century. The invention of technologies including transistors and integrated circuits revolutionized manufacturing, as they automated machines on the factory floor that resulted in reduced effort, increased speed, greater accuracy, and freed up the human workforce for more advanced tasks. The integration of electronic devices and machine automation created a requirement of software systems, fueling the software development market. The software systems paved the way for management processes such as enterprise resource planning, inventory management, shipping logistics, product flow scheduling, and tracking throughout the factory. As expected, the automation of machines and introduction of advanced software systems have evolved over the years as advancements are made in the electronics and IT industries. This is driven by the pressure to reduce costs and speed up production and has led to many companies moving their manufacturing to low-cost countries. This dispersion led to the formation of the concept of Supply Chain Management.
Industry 4.0 was introduced in the 1990s as the internet and telecommunications transformed the way we connected and exchanged information. This technology merged the boundaries of the physical and virtual world, and cyber-physical systems (CPS) further blurred this boundary in manufacturing, introducing an influx of new technologies into the industry. CPS allows machines on factory floors to communicate more intelligently with each other, eliminating physical and geographical barriers.
Industry 4.0 technology uses CPS to share, analyze, and guide intelligent actions for different processes involved in manufacturing. Having all the different machines on a factory floor connected and sending real-time data to the cloud creates the concept of a 'Smart Factory'. These smart machines monitor, detect and predict faults, suggesting preventive measures and remedial action before downtime occurs.
CPS also allows manufacturing processes to be completely virtually visualized, monitored, and managed from remote locations. Industry 4.0 puts machines, people, processes, and infrastructure into a single, connected manufacturing process, which provides businesses with full disclosure over the entire workings of their manufacturing and production. Using this information makes overall management highly efficient.
How Does Industry 4.0 Work?
One of the best ways to understand Industry 4.0 is to think about how it is applied in manufacturing. Here are 3 use cases that will help you recognize the value Industry 4.0 can add to a manufacturing operation:
Supply Chain Management
Industry 4.0 technologies allow businesses to have greater insight, control, and data visibility over their supply chain. Smart manufacturing means companies can deliver products and services faster, cheaper, and with better quality. As more and more businesses use Industry 4.0 solutions for supply chain management, the market becomes more competitive, forcing companies to adopt a similar strategy or risk falling behind.
Industry 4.0 solutions and a connected factory floor can be used to predict potential downtime in machinery before it occurs. Without IoT systems, preventive maintenance must be done manually and happens based on routine or time. Industry 4.0 systems sense problems before they arise and can even provide insight on how to solve issues before they become a problem.
Asset Tracking and Optimization
Industry 4.0 makes it easier for businesses to track inventory, quality, and optimization opportunities related to logistics. Connected manufacturing and the IoT provide employees with visibility over company assets worldwide. Standard asset management tasks such as asset transfers, disposals, reclassifications, and adjustments can be streamlined and managed centrally and in real-time.
Real-world examples of Industry 4.0 technologies
Big Data & Analytics
Advanced computer capabilities now make it easy to sift through massive amounts of data. Data sources can include everything from IoT sensors on factory floors and lighting systems to sales data or supply-chain factors. This data is used to make informed decisions to improve internal processes. Picture this: a shop floor using small sensors connected to every machine in a factory constantly logs and analyzes information both on-site and in the cloud. All this data is fed into a machine learning algorithm that determines equipment’s maintenance schedule. Big data helps factories like this care for their assets, reduce costs, and limit downtime.
Artificial intelligence and machine learning refer to algorithms used in manufacturing to process and learn from data, using it to reach conclusions that were not included in its original programming. A real-world example of how artificial intelligence is used in manufacturing would be in forecasting and predictive maintenance. AI uses the big data we previously mentioned to forecast market changes and predict machine downtime.
Additive manufacturing means creating items layer by layer, adding new material instead of subtracting it. 3D printing is a form of additive manufacturing and has been used by companies like Adidas. Shoe designs were created based on big data and are another real-world example of Industry 4.0 being used by businesses today.
The cloud is a place that can be used for software and data stored on the internet. It is a server, usually located off-site instead of on a local machine for security reasons. The cloud can be used to hold the vast amount of sensor data collected on the factory floor and consumer data gathered through market analysis. In recent years, it has been used for “cloud manufacturing”, which refers to distributed manufacturing across different geographical locations. The cloud can be used to store data from numerous manufacturing plants in one easily accessible location.
Industrial Internet of Things
The Industrial Internet of Things (IIoT) refers to the deployment of small sensors that collect and monitor data in real-time throughout various business processes, including manufacturing. It is a foundational Industry 4.0 technology that can provide detailed insights for decision making at many different levels of the organization. IIoT technology is used in manufacturing to break bottlenecks and drive production. If each piece of machinery is connected to an IIoT device that monitors production, usage, and uptime then the data gathered can be used with a machine learning algorithm to fix inefficiencies.
Using Industry 4.0 technology requires certain security measures to be in place to keep hackers and nefarious agents out of your systems. Blockchain and artificial intelligence are used in modern cybersecurity technology and guard your IIoT devices from internal and external attacks. Manufacturers using Industry 4.0 solutions create plans in case they experience security breaches, which includes enabling protective cybersecurity technology to protect their data and equipment.
